The 29-year-old police officer was shot in the head Tuesday evening while patrolling an area a few blocks off campus, near Martin Luther King Blvd. and Trumbull, in Detroit's Woodbridge neighborhood when he stopped to investigate a man.

Rose was alone in the car with his two dogs. It's standard policy for officers to patrol alone, police said, It's also standard policy not to get the dogs - which are trained for narcotics and bomb sniffing - out and to use them to control a subject.

It is unclear why Rose was in the area – which is off campus. Wayne State police are also sworn Detroit police officers and patrol the area around campus.

Police have not said if Rose was responding to a 911 call, which Lincoln Apartments manager, Betty Evans, said she made. She said she argued with a man on a bicycle, who didn't live there, and called 911 when he wouldn't leave the area. She looked outside as an officer arrived to confront the man on the bike.

"He was outside, in front. The officer was trying to get his hands behind his back. We heard a shot and the officer went down, and we heard two more shots," Evans said.

"I'm just praying everything works out. They have my condolences for this.

"I feel sorry for the officer. I hate the crime that's going on in the city."

There also had been a rash of car break-ins in the area the day before. Wayne State University police Chief Tony Holt said he didn't know how that factored into Rose's decision to stop the suspect. The suspect, who is not being named by the Free Press because he has not been formally charged, was arrested late Tuesday night.

The suspect is known to the Wayne State police and other area departments. In 2011, he was charged with two charges of felony assault involving a police officer, one causing injury, and pleaded guilty, resulting in a 53-day jail sentence, the records show. There also was an incident in 2014, Holt said, although he didn't have details of that.

The shooting is hitting the 65-member police department hard, university President M. Roy Wilson said at a Wednesday press conference. At the press conference, many Wayne State officers, visibly shaken, gathered in the back and exchanged long hugs with each other.

Officials painted a picture of a dedicated officer when talking about Rose.

He was a 2010 graduate of Ferris State University and was one credit short of completing his master's degree in police administration at Wayne State. His first job was with the Richland police department in western Michigan.

“Collin is a 2010 FSU Criminal Justice and Law Enforcement Academy graduate,” Ferris State president David Eisler said in a statement. “We are all deeply concerned for Officer Rose, and we ask that you keep him and his family in your thoughts and prayers.”

He was a K-9 officer, who had both a bomb dog and a narcotics dog. Both were in his vehicle when Rose made the stop last night that led to his shooting.

Holt said it is common practice for the dogs not to be brought out on stops to control suspects.

Rose had worked and done and conducted training all over the state, Holt said. He was also heavily involved in organizing memorials for other slain police officers in the area. Members of many Detroit-area police departments showed up at the hospital following the shooting.

People who live near the scene where Rose was shot said the suspect is a regular recipient of meals handed out three evenings per week from the I Am My Brothers Keeper Ministry about a block away.

"He's just eat his food and took off," said a man who identified himself as Angelo L. "(He would) go outside, smoke a cigarette and just vanish. That was it, just like everybody else that comes down there to eat."

He said he'd seen the man in the area regularly for the past five to six years.

Angelo L. said he was familiar with Rose, who would regularly speak with and help people in the neighborhood, and that he feels "very, very bad for him."

Annette Covington, who was sitting in a vehicle with Angelo, lives near the scene and said the police broke down her door and raided the home, making a mess and tossing her TV and heater on her bed. She said they don't associate with the suspect, but that "we feed and help everybody in this neighborhood."

A man who identified himself as Thad L. said the suspect had been homeless and living in a nearby park. He said he declined to give his full name because he was concerned people associated with the suspect would come after him.
